ADJUSTABLE STOP-TEMPLET.

SPECIFICATION forming part of Letters Patent No. 600,390, dated March 8, 1898. Application filed May 29, 1897. Serial No. 688,774. (No model.)

To all whom it may concern.-

Be it known that I, JACOB W. TRIPP, of New York city, in the county and State of New York, have invented a new and Improved Adjustable Stop-Templet, of which the following is a full, clear, and exact description.

The object of my invention is to provide a templet to be used in cutting miters and fitting mitered joints in moldings, and more particularly for fitting the joints in molded bars where a portion of the bar is beaded, and this portion should be beveled in order to make a proper joint.

The invention consists in the novel constructions which will be hereinafter described, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of my device as applied to a piece of molding or beaded bar. Fig. 2 is a top plan view of the same. Fig. 3 is a cross-sectional elevation taken upon the center line. Fig. 4 is a section taken through the arm where the pivoted stop-bar is connected thereto, and Fig. 5 shows a form of joint for making which my device is especially adapted.

The main part of my device consists of two flanges A and B, which are placed at right .angles to each other, having their inner surfaces made true, so as to fit adjacent sides of a square bar. This piece is also provided with beveled flanges 12 at each end thereof. These flanges are placed at an angle of fortyfive degrees with the contact-surface of the top flange B and at right angles to the side flange A, thus forming a miter-templet similar to the templet ordinarily used in cut-ting bevel-molding and similar stock. The beveled flange 12 is continued upward over the top flange B, forming a guide for the tool which cuts the bevel.

On the upper side of the top flange B is formed a cylinder 11, which receives a bolt or arm 16, which projects at right angles to the contact-surface 15 of the side flange A. This bolt or arm should be accurately located at the middle point between the beveled flanges 12. The bolt 16 is provided upon one side with a longitudinal groove or key-seat 19. The outer end of the boltis also threaded. Mounted upon the inner portion of the bolt 16 is a clamp-jaw 20, which is free to slide upon the bolt, but is provided with a screw 21*, the point of which enters the groove 19 in the bolt 18. This permits the clamp-jaw to slide upon the bolt, but not to rotate thereon. The inner surface of the clamp-jaw is made parallel with the contact-surface 15 of the side flange A.

Near the inner edge of the clamp-jaw 20 a slot 21 is formed adapted to receive the end of a flat stop-bar 23, which bar has a hole through one end adapted to receive the bolt 18.. The slot 21 is so formed as to permit the stop-bar 23 to be extended horizontally in either direction. A nut 27 is threaded upon the outer end of the bolt 18. The nut has a peripheral groove near its inner end, forming a flange 28, and the outer edge of the clampjaw 20 is provided with a flange 22, adapted to enter this groove and thus to lock the bolt and clamp together, so that as the nut is turned upon the bolt the clamp will be moved inward or outward. The stop-arm 23 has its outer end slotted, as shown at 26. A block 24 is mounted to slide upon the outer end of the arm 23 by means of the bolt 25, which passes through the slot 26 and engages the stop-block 24. 1

In the drawings the jaw or arm 20 is shown as applied to a piece 0 of molding. This molding is provided at one corner with a bead O.

In using my device the clampjaw 20 is adjusted until the device will fit snugly over the stock to be beveled. In placing it in position it is moved to the point where the bevel is to be cut, and may then be clamped in position by a turn of the nut 27. This clampjaw serves to hold the templet accurately in position upon the stock and to quickly and firmly secure it thereto. In this manner my device is used as an ordinary templet, except that it is provided with the ad just-able clampjaw 20. required.

In uniting two bars by a miter-joint and at right angles to each other it is often desirable to bevel a portion of the stockas, for instance, where the stock is provided'with a bead such as shown at O in Fig. 2. In using For such use the stop-bar 23 is not thedevice for this purpose the stop-block 24 is adjusted upon the arm 23, so that when it is brought in contact with the end or a shoul der on the stock the beveled surface 12 will be in such position that if a chisel is placed upon the beveled surface the corner of the stock containing the bead may be cut oif, as is shown in Figs. 1 and 2. When the stopblock 24 has been thus adjusted, it is left in this position while the pieces containing this one job are being beveled. In this use of the device the beveling or mitering of the corner does not extend entirely across the piece, but includes only a portion thereof.

The device may be used also for mitering the ends of moldings to form the corner-joints of picture-frames and .also for be'veling the beaded portions of bars which are joined at right angles," such as the central bar of a window-sash. Such bars are usually joined by a mortise and tenon. Where the edges are beaded, the bead should be joined by a bevel in the manner shown in Fig. 5, where 0 represents the bead, and C the miter-joint therefor. In such cases the mortise and tenon are first formed. The shoulder thus formed is utilized for a base from which to locate the bevel of the bead. The stop-block 24 is set at such a point on the arm 23 that when it is placed against the shoulder of the tenon, as shown in Figs. 1 and 2, the bevel-surface 12 will correctly locate and guide the chisel in beveling the bead. Where such work is done in large quantities, it can be by these means much facilitated, as one adjustment answers for all.

In beveling the beaded edge of pieces containing a mortise, as shown in Fig. 5, the stop-block 24 is not needed or used. In this case the bevel is commenced even with the edge of the mortise and extends toward the center of the mortise. The templet can be set by bringing the beveled surface to the edge of the mortise or to the line which is always left at the edge of the mortise. Vhen the templet is brought to position, it is secured by tightening the clamp-jaw 20 upon the side of the bar. In cutting bevels for mortises the arm 20 and stop-block 24 are not used, but are thrown back out of the way. In work of this character it is quite often possible to use the arm 23 and stop-block 24 in this manner to locate a bevel. This can be done wherever there is a shoulder or surface which bears a definite relation to the position of the bevel. The arm and block thus facilitate the work and make it unnecessary to measure the piece for the bevel.

The device may be used without the arm 23 and stop-block 24 as an ordinary templet. It can be used in this way for cutting bevel surfaces upon any object. The particular work in which the stop arm and block are used is in forming the bevel on the ends of beaded bars or moldings which are joined at right angles to each other and where they do not form a miter-joint.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
